Bitumen C240 Description
C240 is a paving grade Bitumen manufactured to AS 2008 Table 2.2 and is suitable for standard sealing and lightly trafficked asphalt applications.
Bitumen C240 Applications
C240 bitumen can be used for all standard spray sealing and lightly trafficked asphalt applications.
|Mixing Temperature||Holding time at Mixing Temperature||Medium term storage temperature||Medium term storage time||Maximum safe handling temperature|
|140-165°C||14 days||130-150°C||30 days||175°C|
|Spraying Temperature||Holding time at spraying temperature||Medium term storage temperature||Medium term storage time||Minimum pavement temperature|
|170-180°C||7 days||130-150°C||30 days||15°C|
During sealing operations, it is normal practice to add cutter oil to the bitumen to reduce binder viscosity to a level at which effective wetting and adhesion of the cover aggregate can take place. The quantity of cutter oil added to the bitumen depends upon the pavement temperature, the daily traffic, and the nominal size of the cover aggregate.
Basic cutting practice for Viva Bitumen C170 bitumen should be as follows:
Parts cutter per 100 parts bitumen measured at 15°C
|Pavement Temperature (°C)||Traffic (veh/lane/day)||Nominal Aggregate Size: 10mm or greater||Nominal Aggregate Size: 7mm or less|
|15 to 20||low (<100) med (100 – 1500) high (>1500)||7-8 5-6 4||7-10|
|20 to 25||low|
|7-8 5-6 4||7-10|
|26 to 35||low|
|4-6 2-4 2-3||6-8|
Bitumen C240 Health & safety
Bitumen C240 is unlikely to present any significant health or safety hazard when properly used in the recommended application where good standards of industrial practice are maintained. Further guidance on Product Health and Safety is available on the relevant Material Safety Data Sheet.
